MANUFACTURE OF o'eoonmeoetasswnne.

sr-eemcammumin part. of Letters 2mm No. 3 7,325. dated am. 2, secs.

Application filed December 36,

To all whom it may concern:

Be it known that I, Aneus'r HAMPRECHI, of Wellsburg, in the county of Brooke and State of West Virginia, have invented ahew and useful Improvement in the Manufacture of Decorated Glassware; and I do hereoydeclare the following to be a full, clear, and exact description thereof.

lily invention in the decoration of glassware consists of a new combination of the process of applying and burning on colors with that of grinding, whereby any desired party-color figure may be produced upon an article of glassware with novel and striking client. The outlines, together with such other lines and parts as are desired to give strength and character-to the design or pattern, are made by-cutting or grinding, and are of a translucent character, the article being made'of clear glass. The body of the design or parts of the same is colored by point ing or otherwise, and the colors are tired or baked in. .The result is a beautiful and unique decoration. It IS applicable to any kind of glassware.-

To enable others skilled in the art to make use of my invention, I will now'describe it by reference to the accompanying drawings, in

which- Figure 1 is a pitcherillustrating the process. Fig; 2 is a view of a piece of glass, showing another pattern. v

The design shown 1!] Fig. 1 is that ol a.vine' The vine a, 'stips having leaves and a flower. ulcs b, edges of the leaves cand flower d, and the veins e of the leaves are all formed by grinding, and are translucent, having a frosted The colored central portions, f, varnishing, or by the article is placed in a suitable oven and or'baking.- Any desired number and arrangement of I the colors may be adopted, thatdbpending entirely on the character of; the taste of the decorator. f

In Fig. 2 I show a piece of glass upon which is a morninggl'ory. Here the sten g, calix h,

and veins tare delineated by grinding,whil e the corolla or petalsk are delineated by colo the design and 1885. Serial No. 185,797. (No specimens.) 7

or tints, whereby thedeiicate hues can be properly represented.

--The process is conducted in the following manner: Any desired article of glassware is taken andcolor applied in spots at the proper points-for instance, for the leaves 0 and iloraer d. This color may he of one or more tints, asmay be desired. The proper =surfacesbeing thus covered, the article is placed in a suitable furnace, and the color or colorsfixed by ing or burnin It is then taken to the catting-shop and the edges of the colored spots ground to form the frosted edges of the leaves a and flower d. The figures thus made have colored centersv and ground outlines.

. connecting-lines in Fig. 3., the vine a, stipnies b, and'veins e necessary to complete the general design are ground in. It is apparent that designs of a great variety canfoe produced in. this way. The wide or body portions are made by first applying a spot of color, and then the outline of the figure is out, as stated, removing any part of the colored surface that may extend to the lines of cut.

designs can be produced; tin-glassware in this way with beautiful and striking e il-cote. The application of all kinds of flowers, leaves,

Partyeoiored I plants, fruits,- insects, geometrical and other figures, faces, and emblems to glassware by this process is contemplated.

It will be noticed that the ground edges of the leaves 0, and the center and edges 05 the flower-d, as well as the calix h, are composed of a series of surfaces or plane figures, x, having an imhricated appearance and a diagonal grain. This is accomplished by presentingthe article to the wheel at an angle to the axis of the, figure and overlapping the mark of the previous cut. I This method. is useful in rep resenting scaly and other inibricated patterns. It gives a vei y handsome effect.

* The coloring need not cover the entire sue face of theclear glass in the bounds of the design, but may be put on portions only of the same.

Nhat l claim as my'invention, and desire to secure by Letters Patent, is

1. The process ofdecorating glassware,whlch consists in applying and baking coloring-mat ter to the; surface at the desired point, and.

iinbriented outline is formed on the surface of the article, substantially as and for the purposea; described.

then grinding the outlines of the desired figure or pattern around said colored Sl1IflC,l-h6l0 by a colored figure with frosted edges or on line is formed on the surface of the article,

2. The process of (lecoz'ai i ng glzlsnwu re, which consists in applying and baking {lOlOI'illgJlliiE- ter to the surface at, the desired point, :nnjl then producing the outline in frosted. inihi-L 1o cated surfaces by grinding around. said. solo Jed hand this 8th day of December, A. D. 1885.
